NOTE: Different vehicles have different diagnostic menus.

A. Read Fault Code
This function can read the Diagnostic Trouble Codes (DTCs) in the ECU memory, quickly identifying the cause of the vehicle breakdown.
Select Read Fault Code, the screen will display the diagnostic result.
NOTE: Retrieving and using DTCs for troubleshooting vehicle operation is only one part of an overall diagnostic strategy. Never replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem. This information can be found in the vehicle’s service manual.

On-Screen Buttons:
a. Freeze Frame: Take a snapshot of specific data streams for verification when the DTC occurs.
b. Help: Tap to view the help information.
b. Code Search: Tap to search for more information about the current DTC online.
c. Report: Tap to save the current data in text format. All diagnostic reports can be accessed from User Info -> My Report -> Diagnostic Report.

B. Clear Fault Code
This function can erase the codes from the vehicle. Please make sure the vehicle’s ignition key is in the ON position with the engine off before the operation.

NOTE:
– If you plan to take the vehicle to a Service Center for repair, DO NOT erase the codes from the vehicle’s computer. If data is erased, valuable information that might help the technician troubleshoot the problem will also be erased.
– Clearing DTCs does not fix the problem(s) that caused the code(s) to be set. If proper repairs to correct the problem that caused the code(s) to be set are not made, the code(s) will appear again and the check engine light will illuminate as soon as the problem that caused the DTC to set manifests itself.

C. Read Data Stream
This option retrieves and displays live data and parameters from the vehicle’s ECU.

CAUTION: If you must drive the vehicle to perform a troubleshooting procedure, ALWAYS have a second person assist you. Attempting to drive and operate the diagnostic tool at the same time is dangerous, and could cause a serious traffic accident.

On-Screen Buttons:
a. Select Page: Tap to select all items of the current page.
b. Select All: Tap to select all available items. To select certain data stream item, just check the box before the item name.
